[mm,v2,16/33] kasan: only define metadata offsets for Generic mode

Commit Message

[e-mail] July 19, 2022, 12:09 a.m. UTC

From: Andrey Konovalov <[e-mail]>

Hide the definitions of alloc_meta_offset and free_meta_offset under
an ifdef CONFIG_KASAN_GENERIC check, as these fields are now only used
when the Generic mode is enabled.
